A nurse is caring for a client who has AIDS. The client states, “My mouth is sore when I eat.” Which of the following instructions should the nurse provide?

Choice A reason: Measuring the apical pulse (at the heart) simultaneously with the radial pulse (at the wrist) by two nurses accurately detects a pulse deficit, which occurs when heartbeats do not translate to peripheral pulses, often in arrhythmias like atrial fibrillation. This method quantifies the difference, aiding diagnosis and treatment, making it the correct approach.
Choice B reason: Comparing carotid pulses at rest and after standing assesses orthostatic changes, not a pulse deficit. A pulse deficit reflects a discrepancy between central and peripheral pulses, not positional changes. This action is irrelevant to detecting pulse deficits, as it does not compare simultaneous heart and peripheral pulse rates.
Choice C reason: Deflating a blood pressure cuff while palpating the brachial pulse is used to measure blood pressure, not to assess a pulse deficit. This method does not compare central and peripheral pulses simultaneously, which is necessary to identify a deficit, making it an incorrect approach for this assessment.
Choice D reason: Assessing both radial pulses simultaneously evaluates symmetry but not a pulse deficit, which requires comparing the apical (heart) pulse with a peripheral pulse. This method misses the central-peripheral comparison critical for detecting discrepancies caused by arrhythmias, making it inadequate for assessing a pulse deficit.

Choice A reason: Frequent nosebleeds are not linked to coarctation of the aorta, a congenital aortic narrowing. They may result from hypertension or nasal issues, but coarctation causes differential blood pressure, with high upper body pressure, not nasal vasculature changes, making this an unrelated finding.
Choice B reason: Weak femoral pulses are expected in coarctation of the aorta, as the narrowing restricts blood flow to the lower extremities. This creates a pressure gradient, with stronger upper body pulses, detectable in infants, guiding diagnosis and management of this cardiovascular defect.
Choice C reason: Increased intracranial pressure is not associated with coarctation, which affects cardiovascular dynamics, not cranial pressure. It may occur in neurological conditions, but coarctation’s primary effect is hypertension above the narrowing, not brain-related changes, making this an irrelevant finding in this context.
Choice D reason: Upper extremity hypotension is incorrect, as coarctation causes hypertension in the upper extremities due to restricted aortic flow. Blood pressure is higher above the narrowing, with strong brachial pulses, while lower extremities experience reduced flow, opposite to hypotension in the upper body.
